Definitions
- a mixing chamber for mixing a gaseous and a liquid
- the present invention relates to a mixing chamber for mixing a gaseous and a liguid component, said mixing chamber being provided with separate inlet connections for the pressurized components for the mixture which is to be formed, and an outlet connection for the formed mixture to a space which is at a lower pressure.
- the invention further relates in general terms to to a method according to Claims 10 of 11, and to bodies or objects produced using the method.
- Fig. 1 is a cross-sectional diagram of an example of a mixing chamber according to the invention
- fig. 2A and 2B are views on an enlarged scale of a part of the mixing chamber
- fig. 3 is a section along the line III-III in fig. 2A of a somewhat modified, form.
- the mixing chamber shown in fig. 1 is part of an aerosol can of which no further description will be given.
- This mixing chamber 1 consists of a cup-shaped lower part 2 and a ring-shaped cap 3.
- the cup 2 is provided on the bottom with a connector pipe for an immersion tube 5 which is immersed in the liquid contained in the aerosol can.
- a collar 7 of the cap 3 fits onto the upper edge 6 of the cup 2, its internal diameter corresponding to the external diameter of the edge 6 while the internal diameter of the portion of the cap 3 interconnecting with the collar 7 being equal to the internal diameter of at least the upper e dge of the cup 2.
- the upper edge 5 of the cap 3 is in sealing contact with a ring sea. 9 , which is part of the distribution valve assembly of the aerosol can.
- the lower end of a hollow stem 10 projects into a central orifice 10 of this ring seal 9, said stem being connected to the spray head of the aerosol can.
- the lower end of the stem 11 rests against a pressure body 12 which is biased upwards by a spring 13 which rests against the bottom of the cup 2, the uppermost position of the stem being defined by an abutting surface which will not be further described.
- the lengthwise bore 14 of the stem 11 is in the present case connected with the exterior on either side through a transverse bore 15. which, in the situation here depicted, is above the ring seal 9.
- the number of transverse bores issuing may be more or less.
- the cap 3 has near its transition to the coiiar 7 a transverse shoulder 16 which rests against the end surface 17 of the cup 2 and is provided with a number of grooves 18 whcih are more clearly depicted in fig. 2. These grooves together with the end surface 17 delimit channels 19 which connect the exterior of the mixing chamber, in which the propellent ispresent, to the interior of the mixing chamber. To that end, the external wall of the upper edge 6 of the cup 2 is provided with grooves 20 which together with the coiiar 7 define passages 21.
- the upper edge 16 of the cup 2 is beve l led on its outside, as is indicated at 22.
- the channels must have a diameter such that
- a total area of the channels 19 of 0.3 mm 2 will be suitable, which, divided over, say, seven channels, leads to channels with a width of about 0,2 mm 2 .
- the number of channels 19 depends on the turbulence to be achieved in the mixing chamber. It is preferable to choose an odd number if the number of transverse bores 15 in the end of the stem is an even one and contrariwise, in order to avoid as much as possible a direct influx from a channel 19 into a transverse bore 15. It is also possible to have the grooves 17 slanted so as to enhance the turbulence.
- Fig. 3 shows a modified example.
- the channels 19 issue into a circumferential groove 23 in the inner wall of the mixing chamber. This has proved to enhance the mixing.
- the groove may also, or instead, be provided in the upper portion of the cup, as is shown in fig. 3 in dotted lines at 23'.
- the mixing chamber is formed of two parts 2 and 3, the various grooves 18 and 20 may be easily formed during injection moulding of these parts, so that inexpensive mass-production is possible.
- Channels of the aforesaid limited size cannot be achieved in properly controllable sizes by conventional methods (such as fillers in injection moulds, laser beams and suchlike), especially in mixing chambers of limited size, as is the case with mixing
- an aerosol can provided with such a mixing chamber 1 will also work satisfactorily if held upside down, so that the channels 19 interconnect with the liquid space and the tube 5 with the propellent gas space.
